A method of contacting s substrate having a surface containing hydroxyl groups
with a non-aqueous solution containing a material having a chrolosilyl group; washing
if desired; coating the substrate with a non-aqueous solvent containing a compound
having a fluorocarbon group and a chlorosilane group or a solvent containing a
compound containing a fluorocarbon group and an alkoxysilane; and baking the substrate
if necessary in order to form a fluorocarbon-based polymer coating film chemically
bonded to the substrate surface. The hydroxyl groups on the substrate surface and
chlorosilyl groups are reacted to form a thin film having a large number of silanol
groups (-SiOH) capable of connecting the polymer coating film to the substrate
to form a heat-, weather-, and wear-resistant film on various surfaces.
